Last October, when Susan Hubbard and her team pulled sleds full of sensitive sensors across the snow near the northernmost point in Alaska, temperatures hovered in the single digits and low teens (e.g., 8–15 °F). Foremost in the researchers’ minds, aside from collecting data on the frozen ground beneath their feet, were two things: keep an eye out for ...

Rock glaciers in the Ulakhan-Chistay ridge (axial part of the Chersky mountain range)
The Ulakhan-Chistay Ridge is interesting by the fact that one of the most extensive mountain glaciations in northeast Russia is located here. In addition, there are widespread specific glacial-cryogenic formations – stone glaciers related to glacial and

Syngenetic sand veins and anti-syngenetic sand wedges, Tuktoyaktuk Coastlands, western Arctic Canada [PDF]
Sand-sheet deposits of full-glacial age in the Tuktoyaktuk Coastlands, western Arctic Canada, contain syngenetic sand veins 1-21 cm wide and sometimes exceeding 9 m in height.

Estimation of subsurface porosities and thermal conductivities of polygonal tundra by coupled inversion of electrical resistivity, temperature, and moisture content data [PDF]
Studies indicate greenhouse gas emissions following permafrost thaw will amplify current rates of atmospheric warming, a process referred to as the permafrost carbon feedback.

Permafrost, or perennially frozen ground, occurs widely throughout the northern half of Canada. Experience has shown that special design and construction techniques are required for building on permafrost in order to avoid disturbing the delicate thermal balance that preserves the frozen ground.

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Permafrost temperature and active-layer thickness of Yakutia with 0.5-degree spatial resolution for model evaluation [PDF]
Based on the map of landscapes and permafrost conditions in Yakutia (Merzlotno-landshaftnaya karta Yakutskoi0 ASSR, Gosgeodeziya SSSR, 1991), rasterized maps of permafrost temperature and active-layer thickness of Yakutia, East Siberia were derived.

When the bottom of the foundation pit is below the groundwater level, groundwater drawdown is required; as a rule, it is extremely expensive. In order to reduce water drawdown costs in areas with consistently low air temperatures we suggest to excavate ...

Mapping Mountain Permafrost Landscapes in Siberia Using Landsat Thermal Imagery
Intensive development of South Yakutia, a mountainous area in the Russian sporadic permafrost zone, must be founded on knowledge about regional permafrost conditions. New permafrost maps for mountainous areas in South Yakutia (the Elkon Mountains and the
